It was believed that the preSl region cotainedthe hepatocyte attachment sites of the virus as well as multiple highly immunogenicT-cell and B-cell epitopes. The antibody response to the preSl peptide was also oneof the most important serological markers of HBV infection.展开更多
[目的]检测乙肝患者血清中乙肝表面抗原大蛋白（Hepatitis B Virus Large Surface Protein,LHBs）、乙肝前S1、HBV DNA,探讨LHBs用于乙肝患者临床诊断的意义。[方法]采用酶联免疫吸附实验（ELISA）检测LHBs以及乙肝前S1,采用化学发光方...[目的]检测乙肝患者血清中乙肝表面抗原大蛋白（Hepatitis B Virus Large Surface Protein,LHBs）、乙肝前S1、HBV DNA,探讨LHBs用于乙肝患者临床诊断的意义。[方法]采用酶联免疫吸附实验（ELISA）检测LHBs以及乙肝前S1,采用化学发光方法检测乙肝两对半,采用荧光定量PCR方法对患者HBV DNA进行检测。[结果]（1）相同乙肝模式患者血清LHBs与HBV DNA检出率比较差异无显著性意义（P〉0.05）;（2）HBeAg阳性患者血清中LHBs与HBV DNA阳性率均明显高于HBeAg阴性患者,差异有显著性意义（P〈0.05）;（3）相同乙肝模式患者血清乙肝前S1的检出低于HBV DNA的检出,两者相比较差异有显著性意义（P〈0.05）。[结论]LHBs可以弥补由于乙肝病毒变异引起的HBeAg检测的不足,LHBs可以反映病毒复制。展开更多
